Mera disappeared during the Battle of London, with things really not looking good for her. At least part of this issue deals with what happened to her. It’s a very nicely done story, and features one of the very rare male characters in the “Bombshells” era. From the ocean, the issue moves to Berlin, where we learn more about what’s been happening to Zatanna and John Constantine. A new character makes her Bombshell debut during that sequence, and there’s the return of the Joker’s Daughter.
